PVC IRRIGATION VALVES

Introduction

Cepex offers a complete range of valves for the irrigation world, including hydraulic valves, angle seat valves (in several versions), and air release valves.

Hydraulic valves

Size range
• From 2" (63 mm) to 3" (90 mm).
Standards
• Available Standards: ASTM, British Standard, Metric.
• Threaded versions: NPT & BSP.
Working pressure
• See chart.
Features
• Valve closes by diaphragm when water flows into the control chamber.
• Valve opens when the fluid in the control chamber is released through either a 3-way ball valve or a solenoid.
• 100% factory-tested.
• Hydraulic operation.
• Made of PVC-U with NBR diaphragm.
• Good mechanical strength.
• Resistance to many inorganic chemicals.
• Excellent flow characteristics.

Air/Vacuum Relief Valve

Size range
• 1½" (DN 40).
Standards
• Available Standards: ASTM, British Standard, Metric.
• Threaded versions: NPT & BSP.
Working pressure
• See chart.
Features
• Double benefit: this valve extracts the air from pipes as they fill with fluid and protects them against crushing by allowing atmospheric air to enter at even the slightest drop in pressure.
• Mainly used in irrigation systems.
• Especially applicable in facilities with changes in level and those with long pipe sections (500 m / 1,640 ft or more).
